Tips and tricks
• The main screen of the app contains the activities that you created.
• The Skills menu item allows you to manage skills (create, view, edit, delete).
• The Categories menu item allows you to manage categories (create, view, edit, delete).
• The Trends menu item displays some neat charts.
• The Store menu item allows you to manage products / rewards (create, view, edit, delete).
• The Transactions menu item shows the expense / income coin transactions.
• There is one category created by default: General. You can edit it, and you can add more categories by pressing on the + button when on Categories page.
• Icons for skills, categories, and products are mandatory.
• You can add activity only when you have at least one skill defined.
• Store is for user-defined rewards (see explanation below).

Store
The use of the store is completely optional. The main aim of it, is to allow the user to define some rewards for time spent developing a skill.

Examples:
• Gaming - you can purchase an hour of gaming using X coins that you got from developing a skill.
• TV Shows- you can purchase an episode of TV Shows using X coins that you got from developing a skill.
The idea is to allow you to define rewards for your time spent developing useful skills.

More icon packs will be added in the future.
More gamification features are going to be added in the future (feel free to suggest them).

The free version allows you to have a maximum of 7 skills at a time, everything else is not restricted.

User Reviews

Mastery is praised for its simplicity, reliable time-based tracking, and icon-driven organization with no ads. Users love the data and motivation, but repeatedly warn about unreliable backups, no cloud sync, and a lack of updates. Feature gaps (export, trends, customization) and occasional stability issues further weigh on perception. Overall, strong concept and UX when working, but significant data-retention and development concerns.
Pros
  • Simple and intuitive to use for daily tracking
  • Great focus on time spent with meaningful data and progress insights
  • Icon visuals help distinguish between skills and improve organization
  • Ad-free experience and upgrade is considered worth it
  • Backup options exist (local backups and Google Drive) to retain data
Cons
  • Unreliable backups and restore process; users fear data loss and cannot trust the backup system
  • App appears abandoned with no updates for years
  • Lacks cloud syncing and easy cross-device backup/restore
  • Limited/customizable icons; requests to upload own icons and more icon options
  • Missing features like exporting data to Excel, trend analysis across all skills, and a home/overview page; occasional stability issues

I use this app so many years. It's simple and brilliant. I only wish it had more icons variations because I use it not only for skills but day tracking. Sad it has been abandoned.

A fantastic application I have been using this since 2018, keeping track of every second I've spent. It does a good job of helping me quantize my day and accomplish more productive stuff. I really really wish it was still being updated, as it's extremely basic. I want more graphs and better summaries of larger spans of time. If I want to see how I've spent a year, I have to manually add every minute from every skill. I also wish I could access my save data and adapt it to my own program.
